.To all whom t may concern.-

Be it vknown that We, JOSEPH A. WHITE and JOHN W. GRAY, of Hartford, in the county of Hartford and State of Connecticut, .have invented certain new and useful Improvements in Sprinklers, of which the following is a specification.

Our invention relates to devices for sprink- .lingplants and clothes and for other like uses;

and it consists in a novel construction, whereby the water is allowed to enter freely to rapidly ll the body of the sprinkler, but is permitted to escape only through the ne perforationsof the sprinkler-rose or perforated disk.

Prior to our invention sprinklers have been made having special supply-inlets provided with independent `inwardly-ppening l valves;

` but by our improved construction we are enabled to dispense with such independent valves,

and to cause the disk, plate, or other body in which the perforations are formed, to serve also as the inletvalve.

In Vthe accompanying drawings, Figure 1 is a perspective view of our improved sprinkler;

water-tight joint between the bowl and cap. Just Within the circle of rim or edge c, we forni a series of elongated holes, e, of a size to permit water to ow through them freely and rapidly to ll the bulb A. These holes e fall within the Width of flange cl of cap D, and when the disk lies flat upon said flange they are closed thereby; but if the disk be lifted up olf said flange the holes are opened and water is permitted to enter freely through the large central opening of the cap and to pass thence through the holes e and into the bulb.

When pressure is applied to the bulb, the water bearingupon the disk presses it rmly down upon the flange d, thus closing the holes e and compelling the water to escape through the fine perforationsf alone. It will thus be seen that when the bulb is compressed and the bowl or sprinkler is immersed in water the expansion of the bulb will cause it to iill quickly with water, and that upon again compressing thejbulb the water will be forced out in afine disk is made conical and is fitted to a seat ofY like form.

Stops g, projecting inwardly from the bowl or shell B, limit the rise of the disk eating with its interioris a belllshaped sprinkand prevent its displacement. The action is 8 5 35 ler-body, B, having a suitable neck, a, for precisely the same as under theprevious conattachinent to the bulb, and an external screwstruction,vv except that the water flows inward thread, b, around itsV lower edge, when the between the periphery or edge of the disk and device is held as in Figs. l and 2.
